INS Sumitra, 105 meter long Naval Offshore Patrol Vessel (NOPV) was launched on December 06 at Goa Shipyard Ltd (GSL). The same length of OPVs constructed by GSL for Indian Coast Guard are designated as AOPV (Advanced Offshore Patrol Vessel). Construction for three NOPVs were approved by the government in March 2005 with an option to construct fourth one that was finalized in 2006 (project cost INR 2452 crores)

The 44th Annual Report and the audited Accounts of GSL for the year ended March 31, 2010 highlights that “the construction of Naval Offshore Patrol Vessel-Yards 1196 & 1211 are in advanced stages. The delivery of Naval Vessels (Yards 1194, 1195, 1196 & 1211) are affected due to delay in supply of gear boxes by the supplier. The Company has taken necessary steps to curtail the delay by procuring the gear boxes from alternative source”.
